NEW AND LITTLE-KNOWN INDIAN BUTTERFLIES. 179 



in the Western Himalayas is markedly crepuscular, I have seen 

 specimens over and over again flying up and down a short distance 

 of the bed of the Simla river with immense rapidity, so fast that 

 the eye can hardly follow them, settling on a leaf for a second and 

 then flying off again, long after the sun has set. All that are known 

 to me have the hindwing more or less spotted. C. eligius, Cramer, 

 was described, from Surinam in South America, and Felder states 

 that he has received a specimen from Venezuela. The similarity 

 in the markings of the forewing of this species to those of C. 

 maculosa, Felder, from Shanghai, is not a little remarkable. The 

 transformations of only one species are known, those of C. 

 spilothyrus, Felder.

Habitat : Surinam. 



Note — From the figure and description this species appears to me
